One thing that I've gotten in the habit of checking on these older cars is the ignition switch when all of the obvious things check okay.
This switch is clamped together and over time the clamp (actually little metal fingers) can let loose. If the switch isn't held tightly together it will act up intermittently by not allowing power to flow to the starter solenoid.
You can try reaching down to the switch (on top of the column near your feet) and squeezing the switch to compress it as you turn the key. If it appears loose, or you get an intermittent electrical response as you do this, the switch needs to be replaced or worked on.
Also try moving the ignition rod that goes between the key switch (at the top of the column) and the ignition switch along the top of the column. The ignition switch is held onto the column with some small sheet metal screws that can work loose. If they work loose, it will allow the entire ignition switch to move instead of the internal contacts of the switch which can again result in intermittent continuity problems.
Good luck... GUSTO

Uhh..they were thinking that all new Corvettes would be in the 'boneyard' in 10 years time.... 
Only folks like us would expect 40+ year-old stuff to still be working.
